Abstract : Little information is available on the population growth and areal coverage rates of the tropical and subtropical seagrasses shoalgrass, manatee grass, and turtlegrass. However, such data are needed to manage restoration of these systems. In this study, seagrass transplants were conducted at sites across a broad geographic area in order to assess seagrass shoot generation and coverage rates under different environmental conditions. The environmental factors considered were temperature; salinity; light attenuation; water depth; hydraulic regime; sediment type, fluctuation, and depth, and biotic disturbance of these factors, temperature, sediment fluctuation, sediment depth, and biotic disturbance were seen to affect transplants biotic factors were probably most influential in transplant survival and coverage through shading, temperature increases due to reduced circulation, excavation, and grazing.
